Definitions

  • the invention relates to the technical field of optical communication systems using polarization division multiplexing, and in particular to the transmission of optical packets or bursts.
  • EP-A-2273700 teaches methods for speeding up convergence of a polarization demultiplexing filter in a coherent receiver adapted to optical packet reception. These methods involve the generation of optical packets comprising a header section including a single-polarization optical signal and a payload section including a polarization division multiplexed optical signal. To generate such an optical packet, EP-A-2273700 teaches methods that require turning on and off the drivers of MZ modulators and changing the bias of Mach-Zehnder (MZ) modulators at a very high speed between the header section and payload section.
  • MZ Mach-Zehnder
  • US2010150555 teaches a method and an apparatus that are provided for polarization demultiplexing for a Polarization Division Multiplexed (PDM) signal stream in the optical domain.
  • the optical PDM signal stream includes a first channel representing a first data stream and a second channel representing a second data stream, a time delay between the first channel and the second channel.
  • a Polarization Beam Splitter (PBS) demultiplexes an optical PDM signal into the first channel and the second channel.
  • An associated processing block obtains one of the channels and provides a Polarization Controller with for a control signal corresponding to the power level of the low frequency portion of the RF spectrum of the channel obtained. Based on the control signal, the Polarization Controller adjusts a state of polarization of the optical PDM signal stream that is provided to the PBS for demultiplexing.
  • US2010054738 teaches a control apparatus including: an output monitor which monitors polarization-multiplexed output light output from a polarization multiplexing light modulator which modulates light of two systems independent of each other, polarization-multiplexes light signals of the two systems subjected to the light modulation, and outputs the polarization-multiplexed light signals; and a control unit which controls a delay time difference at a stage where the light signals of the two systems forming the polarization multiplexing light modulator are polarization-multiplexed based on a monitor result of the output monitor.
  • the control apparatus controls a delay time difference between polarization channels easily or surely.
  • the invention provides a method for transmitting digital data on an optical channel, comprising:
  • such a method may comprise one or more of the features below:
  • the invention also provides a method for generating an optical packet on an optical channel, the optical packet comprising header section including a single-polarization optical signal and a payload section including a polarization division multiplexed optical signal, the method comprising:
  • the method further comprises changing an operating mode of a baseband signal generation module between the generating of the header section and the generating of the payload section.
  • the method further comprises generating a second single-polarization optical signal of the header section with a similar method, wherein third portions of the first and second baseband digital signals are generated in a correlated manner with a different correlation from the first portions of the baseband digital signals, so as to obtain the second single-polarization optical signal of the header section in a constant State-Of-Polarization orthogonal to the constant State-Of-Polarization of the first single-polarization optical signal of the header section.
  • the invention also provides a optical transmitter for generating polarization division multiplexed optical signals, comprising:
  • the optical transmitter further comprises a packet forming module for forming the first and second polarized optical carrier wave components as an optical packet.
  • aspects of the invention stem for the observation that changing the bias of MZ modulators at a high-speed may generate undesirable transients likely to impose severe limitations on the quality of the modulated optical signals.
  • aspects of the invention are based on the idea of operating PDM optical transmitters to selectively generate single-polarization or dual-polarization optical signals without changing the bias of MZ modulators.
  • Transmitter 1 comprises a laser source 2 to generate an optical carrier wave at a selected wavelength suitable for WDM transmissions.
  • a beam splitter 3 splits the optical carrier wave into two carrier wave components propagating in respective waveguides 4 and 5.
  • a respective optical modulator 6 and 7 is arranged on each of the waveguides 4 and 5 to impart a modulation on the corresponding carrier wave component as a function of respective baseband signals 11 and 12, which are generated by a baseband signal generator 10 at the same data-rate.
  • Optical modulators 6 and 7 may be any type of modulators.
  • optical modulators 6 and 7 are MZ modulator arrangements adapted to generate PSK modulations, e.g.
  • the baseband signals 11 and 12 may comprise NRZ-coded signals driving MZ modulators so that each signal transition causes a 90° or 180° phase-shift in a corresponding carrier wave component.
  • a polarization beam combiner 8 selects an x-polarized component of the modulated carrier wave component coming from waveguide 4 and a y-polarized component of the modulated carrier wave component coming from waveguide 5 and superposes both polarized components into an output waveguide 9, e.g. an optical fiber connected to a communications network.
  • x and y refer to two orthogonal states of polarization defined by the physical structure of the polarization beam combiner 8, as known in the art.
  • the modulated carrier wave component coming from waveguide 4 is denoted by E in,x and the corresponding baseband signal 11 is denoted by x-data.
  • the modulated carrier wave component coming from waveguide 5 is denoted by E in,y and the corresponding baseband signal 12 is denoted by y-data.
  • this principle is used to transfer essentially independent streams of data on the respective field components E in,x and E in,y so as to substantially double the data-rate compared to a single-polarization transmission at the same baseband rate.
  • the SOP of the output optical signal E keeps changing and the instantaneous SOP depends on the data-streams x-data and y-data at any given instant.
  • Eq. (1) E in , x x ⁇ + y ⁇ , i.e. the SOP of the output signal E is constant and the output signal ⁇ is a linearly polarized field along direction x ⁇ + ⁇ .
  • E ⁇ E in , x x ⁇ ⁇ y ⁇ , i.e. the SOP of the output signal E is constant and the output signal ⁇ is a linearly polarized field along direction x ⁇ - ⁇ .
  • optical transmitter 10 can be operated to generate a single polarization signal along direction x ⁇ + ⁇ or a single polarization signal along direction x ⁇ - ⁇ or a dual-polarization optical signal just by changing the binary content of the baseband signals 11 and 12 without modifying the operating point of the modulators 6 and 7.
  • the above principle can be exploited to generate optical packets having a PDM payload preceded by a single-polarization header intended to speed-up convergence of a polarization demultiplexing filter in a coherent receiver, as known in the art.
  • the packet header may include one single-polarization section or two different single-polarization sections having orthogonal SOPs.
  • a PDM header section can be added to refine filter convergence at the receiver before the payload is received.
  • An embodiment of such a packet header 20 with three sections is schematically shown on Fig. 2 as a function of time.
  • header section 21 comprises a linearly polarized field along direction x ⁇ + ⁇
  • header section 22 comprises a linearly polarized field along direction x ⁇ - ⁇
  • 23 denotes a PDM header section.
  • PDM section 23 can be a packet payload.
  • optical transmitter 10 may comprise a packet shaper (not shown) in the form of a semiconductor optical amplifier (SOA) or other optical gate arranged within laser source 2, between laser source 2 and beam splitter 3 or at any other suitable location.
  • SOA semiconductor optical amplifier
  • FIG. 3 there is shown another embodiment of an optical transmitter 101 adapted to selectively generate single-polarization and dual-polarization signals, in particular in the form of optical packets. Elements which are similar or identical to the embodiment of Fig. 1 are designated by the same numeral increased by 100.
  • SOAs 30 and 40 are mounted on the waveguides 104 and 105 respectively.
  • Each SOA 30 and 40 is operated as an optical gate under the control of a gating controller 50 to selectively extinguish the corresponding carrier wave component or pass it to the polarization beam combiner 108.
  • the gating controller 50 controls the switching state of the SOAs as follows:
  • optical gates other than SOAs can be arranged and controlled in the same manner as SOAs 30 and 40, such as silicon photonics optical gates.
  • the modulators 106 and 107 are QPSK modulators comprising two arms, an MZ modulator in each arm and a 90°-phase shift in the lower arm.
  • Other types of modulators can be used in the same manner.
  • x-data and y-data are generated as independent data streams that do not have a long-lasting correlation.
  • coding techniques and protocol functions can create temporary correlations between signals, i.e. as a result of redundancy coding, frame retransmissions, etc.
  • control units and signal generation modules could be e.g. hardware means like e.g. an ASIC, or a combination of hardware and software means, e.g. an ASIC and an FPGA, or at least one microprocessor and at least one memory with software modules located therein.
